I can't use any window manager except TWM and XFCE.
I've tried IceWM and Rox desktop and some other one, the trouble is
they install and start up ok but when I exit the desktop the system
just hangs, nothing works.

I have to turn off the computer, this doesn't happen if I use TWM and XFCE only if it is something else, any ideas? thanks.
